DRAG ATTACHMENT FOR FLOWS.

Specification of Letters Patent.

Patented Mar. 21, 1911.

Application filed November 29, 1909. Serial No. 530,419.

To all whom it may concern:

Be it known that I, JOHN DENGEL, machinist, a citizen of the United States, residing at Madison, in the county of Dane and State of Wisconsin, have invented new and useful Improvements in Drag Attachments for Plows, of which the following is a specification.

The present invention relates to improvements in drag attachments for plows, and is especially applicable to the class of riding plows.

The object of the invention is the provision of means for removing a drag, which may be a toothed harrow, rotary device, or other implement, from operative position, when used in conjunction with a riding plow. The devices by means of which this result is accomplished, are adapted to swing the drag attachment toward the seat of the machine and the entire weight of the drag attachment is carried over directly against the frame of the plow. When in this position the weight of the drag is centrally dis posed with relation to the frame of the plow, and tipping of the plow, by reason of the weight of the drag, is thus eliminated.

To this end the invention consists in certain novel features of construction and combinations and arrangements of parts of the means for connecting the drag with the plow as will be hereinafter more fully described and pointed out in the claims.

In the accompanying drawings, I have illustrated one example of the physical embodiment of my invention, constructed according to the best of the several modes I have so far devised for the practical application of the principles.

Figure 1 is a perspective View of a riding plow shown in dotted lines, the device embodying the features of my invention, a harrow, and parts of the plow frame, being illustrated in full lines. Fig. 2 is a perspective view, enlarged, showing the device for connecting the drag attachment with frame of the device. Fig. 3 is a transverse section of Fig. 2. Fig. 4 is a side view of part of Fig. 3. Fig. 5 is a detail View of the joint between parts of the attachment. Fig. 6 shows a part of the plow frame in section and one of the operating parts of the attachment secured thereto. Fig. 7 is a face view of Fig. 6. Fig. 8 shows another operating part of the attachment secured to the plow frame. Fig. 9 shows the frame bar in section, with the device of Fig. 8 attached thereto, and Fig. 10 is a rear perspective view of the implement lifting device.

In the drawings I have illustrated in full lines so much of the plow frame as is necessary for a proper understanding of the invention, the main frame 1 and seat 2 being essential for the attachment and operation of the device. In this instance I have illustrated the drag as a toothed harrow 3, but it will be understood that a rotary or other implement may be utilized with equal facility in this connection.

The novel attaching means comprises essentially the two rods or bars 4 and 5, which are pivoted with universal joints 6 and 7 respectively, to the frame of the plow, loosely connected to each other at 8, and flexibly connected to the harrow by means of the braces 9. The braces 9 are coupled with the harrow frame at one end and their other ends are fixed to the rotary member 10, upon which the plate 11 of the coupling is imposed. This coupling admits of a wide range of adjustments and its construction enables the operator to use the harrow attachment at either the right or left side of the plow.

The plates 10 and 11 are held together by bolts 12 which are passed through circular slots 13 in the plate 11 and secured at the under side of plate 10 by nuts. A central base 14 on plate 10 projects into a complementary recess in the upper plate and forms a bearing for the rotary movement of the lower plate. The plate 11 is cast with an integral sleeve 15 having a bore to permit the passage of bar 4 and is provided with set screws 15 for adjustably securing the coupling on the bar. A hollow depending shank'16 is cast on the lower plate 10 for the reception of the bolt 17 which is coupled to the harrow frame at 17 and may be adjusted vertically by screw 17. The two bars 4 and 5 are connected together by means of the bracket 18 which is rigidly secured to the bar 4: and is provided with an enlarged opening 19 through which the 1 bar 5 is.

passed. Collars are secured at each side of theopening in the bracket, and the opening-19 is of such diameter as to permit a slight play of the bar 5 therethrough, butprevents the passage of either collar 20. 1

Figs. 6, 7 8 and 9 illustrate more 'eompre-' hensively the pivoted connection between theattachment and the frame of'theplowl Referring to Figs. 6 and 7 more especially, it will be seen that the bracket2l which is clamped by meansof the plate 22 and suitable nuts and :bolts, to the plow frame, is

formed with a perforated lug 23 for the re ception of the eyebolt 24:, and'through the eye ofthe bolt 24 the bent end 25 of the bar 5 is passed.

A sleeve v mitted'to turn in a 31 is formed by curling the end of said plate, and in this sleeve the end 32 of the bar dis journaled. By this arrangement of parts the plate 29 is perhorizontal plane and the end 32 0f bar 4 may turn in a vertical plane. Thus the pivot 30 allows one possible motion", the pivot 32 a second motion, and the pivots 24 and 25, make possible the motion of'the other parts.

The swinging over, against the frame, of the implement tends to preserve the equilibrium ofthe plow frame while in use, and thus eliminates a serious objection, as tipping of the. plow invariably occurs when using a device which merely lifts the drag verticallyfrom its operative position. From the above description takenin connection with the drawings, it is evident that I have produced an attachment which fulfils the purposes set forth, and the invention,

as thus embodied and used has proved highly eflicient and satisfactory.

Having thus fully described my invention,

what I claim as'new and desire to secure by Letters Patent is 1. The, combination with a plow frameof a pair of bars independently and loosely connected thereto to permit swin ing the bars overtoward the frame, an a justable sleeve on; one of the bars, and a link loosely connecting said sleeve with the other bar.

The combination with a plow frame and ';a drag attachment, fof a pair of bars loosely connected to the frame by universal joints, an adjustable connection between one of said bars and the drag attachment,an adjustable coupling between saidbars, and means for swinging said attachment upward and over toward the plow frame.
